What are the ups downsides of mecanum wheels
We have mecanums and they work very well. Omni wheels climb better, but we can still climb and if somebody tries to push you off from the side you can strafe and keep them back. You can see our reveal that we recently posted and see how we work with them.
@dchoi77 Mecanum Wheels provide the ability to shuffle and slide horizontally with a strafe, and is ill equipped to turn as well as other options. I am not sure how the mecanums compare in terms of climbing the platforms, but it would seem that less grip would be applied with them compared to the regular 4" wheels.
@James6555 VERY difficult to climb, but awesome for adjusting to line up your shot. Personally we use them on our robot and it is very useful because it is critical to line up good for our double catapult. We had to get creative to climb. And again it is pretty bulky.
Do you have a picture of your Mecanum Drivetrain.
